A As shown more particularly in Figure 1, any 5disk or f piece 16a is provided with a scr w kind of advertising indicia65 may be applied to the opposite faces of the vane and since the vaneis movable at all times because of air currents the vane makes anexcellent advertising medium due to the movability of the vane forattracting the attention of a passer-by. a

The inner end of the vane 56 will be moved in accordance with thedirection of the wind and will tendlto direct the air currents into theopening in the window-frame when one of the windows has been raised. Thespring 60 will return the vane to its normal inoperative position whenthe air currents have ceased or when the air currents are notsufficiently strong to move the vane against the tension of the spring60. the maxi-- mum position of the vane would be in parallel relation tothe wall 10 of the building.

A coil spring may be located in the bearing 30 and have one endsecuredto the pintle 36 and the other end fastened to the bearing. Inthe event of a very high wind or storm, the vane will line up with thedirection of the air before the wind becomes strong enough to damage thewindow, the vane acting as a safety valve both ways. The distancebetween the outer end of the frame and the point of connection betweenthe pintle 36 and the rod 50 of said frame is approximately one-thirdthe-length of the frame so that the greater portion of the vane. willswing before the openingin the window. The remaining or lesser. portionof the vane acts as abufier and inconnection with the spring 60 operatesto stabilizethe vane when it has'reached a state of rest or anapproaching state of rest.

I claim: V

1. An air deflecting device for windows comprising a supporting rodextending outwardly at right angles to a window, means for securing therod in position, a hollow bearing at the outer free end of the rod andhaving an open upper end, a pintle vertically disposed in the bearingand provided with an annular flange, a shoulder in the bearing andsupporting the flange and pintle, a

closure for the bearing and co-operating with the shoulder to retain thepintle in position, a vane carried by the pintle, and a spring forretaining the vane normally in vertical alinement with the supportingrod.

2. An air deflecting device for windows comprising a supporting rod,means for securing the rod to a window, a bearing at the outer free endof said rod, a pintle mounted in the bearing, a frame secured to thepintle intermediate the ends of the frame, a vane carried by the frame,and a v spring for retaining the frame and vane normally at-right anglesto the plane of the window, the spring" being connected to thesupporting rod and frame and inwardly of the pintle.

3. An air deflecting device for windows comprising a supporting rod,means for securing the rod to a window, a bearing at the outer free endof said rod, a pintle mounted in the bearing, a frame secured to thepintle, a vane carried by the frame, a spring for retaining the frameand vane normally at right angles to the plane of the window, the pintlebeing connected to the frame outwardly of a vertical line passingthrough the center of the vane, the ends of the spring being connectedto the rod and frame at points upon opposite sides of the vertical linepassing through the center of the vane.

4; An air deflecting device for windows comprising a supporting rod',means for securing the rod to a window,. a bearing at the outer free endof said rod, a pintle, mounted in the bearing, a frame secured to thepintle, a vanecarried by the frame, a spring for retaining the frame andvane normally at right angles to the plane of the window, means forremovably retaining the pintle in the bearing, said pintle beingconnected to the frame at a point which is located at approximatelyone-third the length of the frame from the outer end of said frame. 7
